Help troubleshooting sager/clevo NP6370/W370ET Wont Boot

Model: sager/clevo NP6370/W370ET

I was swapping out the lcd cable, everything was working fine. I ending up re-routing a few cables to make it a cleaner install.
Now the notebook won't post. I get the power light, vga light, and bluetooth light on only.
I tried resetting the cmos, by pulling the battery.
Fan for the cpu/gpu will start up for 20 seconds, then shutoff, along with the notebook

Any troubleshooting help would be much appreciated.

 

Try reseating any cables you may have removed. If they look like they are connected properly re do it anyway. If one isnt connected properly you can usually tell by the way it came out easily so do remove them all til you find the one.

 

The only cables I disconnected, were the lcd cable, which I replaced and the keyboard cable, I will try re-seating both of them.

 

but you said you also "re-routed" some cables. could have pulled one out of its connection. might as well check those too.

 

Double checked everything, pulled out all cables, plugged back in nothing. The light does turn on when I plug in the AC adapter, if that makes any difference.
Any other suggestions, or maybe the mobo is toast.

 

Theres always a chance a little static discharge from you damaged the motherboard while you were working on it but they are pretty robust. I wouldnt give up on it yet. If it was working fine before you took it apart its gotta be a cable if not a cable then the motherboard could be dead. What do you mean you plugged back in nothing. Did you pull out all the cables then not plug them back in?

 

Haha sorry typo. I meant to say unplugged all cables, then plugged them back in. I will go through all the cables again.

 

Reseat the memory and hard drive also. If that doesn't work, then pull out hardware. Pull out memory until you have just one memory stick, try different sticks, pull out the optical drive and the hard drives to see if you get an error message. Are the cpu and gpu still seated well?

 

Yeah I have 3 sticks of ram, so I'm trying to see it if it will post with just 1 stick in. Also trying with and without the hard drive. Gpu is soldered to the mobo, I reseated the cpu.
